, This invention relates to radiators.

i It is among theobjects of .the'present invention to provideaa pressureresponsive device for use in radiators whereby cold air within the radiator is entirely expelled through the air valve before steam strikes the valve to heat the same and 'close it.

A further object of the present invention is to provide a spring-urged valve within a. radiator structure whereby it will be closed upon the initial admission of steam to the radiator, thus acting as a baflie to provide for the expulsion of all of the cold air within Other objects and features of the present invention will be apparent from a consideration of the following specification taken in conjunction with the accompanying drawings, in which Figure l is an elevational View, partly 1n sect-ion, showing a radiator embodying the present invention, and V I Fig. 2 is a'detail view of the device of the and Fig. 3 is a detail transverse section of the valve rod and baffle disk assembly.

Referring more particularly to the drawings,-it will be seen that the present invention 0 is applicable to various types of steam heating radiators. The. radiator shown in Fig. 1

and indicated by the numeral 10, is the conventional heater type of radiator formed by a plurality of radiator sections having intercommunication at their upper and lower ends. The radiator shown in Fig. l'is supv I preferably mounted to close the upper joinplied with steam through a supply pipe 11 and cold air is adapted to be driven from the I cold air therethrough but which is operated In the; operation of the device, seen that steam will be supplied through the pipe ll' and in the normal operation ofthe xradiator itwill pass upwardly in the first section as indicated by'the arrows in Fig. l.

in desired manner, as by thermostatic con- 4 trol, to close when steam strikes the valve.

0 which extends therethrough, the disk and steam'will'pass across through the 'top joinrod being :coupled by a suitable washer 16 andcotter pin 1?. Mountedupon the rod 15,

aba'se member 18 is provided, which is adapted to be seated in the normal closure plug 19 of the end section 20 of the radiator. The plug is centrally bored to receive the opposite extremity2l of the rod 15flfor suitable limited movement therein, the base 18 being adapted to secure the valve assembly within the plug'19. Mounted between the base 18 and the disk 13, a coil spring 22 is provided, which, ifl'd'esired, may be adjustable to vary the spring tension applied to the disk'13. the radiator before steam strikes the air valve and closes it.

For preventing the passage of steam ing member 25 is formed of asbestos or equivalent rod packing material and is adapted to'snugly embrace the'stem 15. Its forward face abuts the rear face of the disk 18. ,The packing 25 is urged toward the disk and inwardly toward the rod 15 by a concave washer 26 which receives thereagainst the spring 22, whereby tension of thespring is applied therethrough to the disk 13. The

concave. design of the washer 26 provides pressure at the outer edge of the washer, the line of force of .thefpressure being perpendicular to the surface of the washer, whereby the pacl zing will be urged towardthe stem as wellas toward the back of the'disk. Thus a tight seal is provided which, at the same timeypermits movement of the base with respect'to the disk, thus to compensate for use of the device in various sizes of fittings. As shown in Fig. 1, the valve assembly is the intermediate sections. It will be understood that" the. exact position of the valve assembly as here shown is not essential and may-be positioned between other intermediate sections ifso desired. i

it will be In the normal operation of radiators theing nipples of the sections and downwardly in the end section 20 until it strikes the valve 12, thus closing the valve. In such operation it will be seen that cold air will be trapped in the various end sections below the valve 12.

By the use of the present invention it will be seen that the baffle or valve will direct steam downwardly in the intermediate section next the end section as indicated by the arrow, and such downwardly moving steam will drive before it the cold air. In the end section 20, the cold air will move in the direction of the arrow and will be entirely expelled through the valve 12 before steam strikes the valve.

In the operation of the device, it will be understood that the disk 13 and the packing 14 do not normally move from their seat against the joining nipple 23. The arrangement is such, however, that the baflie disk and the base 18 have respective movements, thus to compensate for use in various types of fittings and in fittings having different dimen- SlOIlS.

From the foregoing it will readily be seen that the present invention provides a novel, simple and improved bafile for steam radiators. It will be understood that the inven tion is not specifically confined to structural features as here presented, nor to the exact location of the device as here illustrated. Numerous changes, modifications, and the full use of equivalents may obviously be resorted to without departing from the spirit or scope of the present invention as outlined the appended claims. It will be particularly noted that the device is easily applied through the opening for the plug 19 and that the device may be removed or adjusted by simple removal of the plug 19.

lVhat is claimed is:

1. A radiator, including a plurality of sections having intercommunication at their upper and lower ends, and pressure responsive means in the passage between the upper ends of one pair of adjacent sections, for the purpose of clearing air from the radiator.

2. A radiator, including a plurality of sections having intercommunication at their upper and lower ends, and pressure responsive means in the passage between the upper ends of one pair of adjacent sections, for the purpose of clearing air from the radiator, said means including a spring pressed axially movable disk.

3. A radiator, including a plurality of sections having intercomrnunication at their upper and lower ends, a bafile member between the upper ends of one pair of adjacent sections, said baflie member being axially movable, and spring means for normally seating.

said bafiie member against one of said sections.

4. The combination with a radiator, of a pressure responsive device having one end thereof fitting in a recess in the radiator to thus hold the device in position, and a spring actuated valve member on the other end of the device to control a passage between two sections of the radiator, whereby the air withing the radiator may be entirely expelled by directing incoming steam through the radiator in a predetermined manner.

5. The combination with a radiator, of a pressure responsive device positioned in relation to a passage between two sections of theradiator to direct steam through the radiator to expel all the air therefrom, said device member comprising a valve disk, a valve stem for supporting said disk, spring means urging said disk to seal said passage, and a sup port for said stem, said support comprising a disk removably receivable within the closure plug of one of said radiator sections.
